A flexible factor was introduced to the fuzzy control model, which can selfadapt and adjust the universe of discourse in the fuzzy control and the workpiece peripheral speed vw was selected as control variable.

采用论域自调整策略和模糊控制理论建立了纵向磨削的控制模型，选择工件的转速vw作为控制变量。

It is proved that these two types of fuzzy controllers are equivalent to the variable structural combinations of nonlinear PI controller and nonlinear control offset. Moreover, the outputs of these fuzzy controllers are monotonically increasing, continuous, and bounded with regard to the corresponding universe of discourse.

基于此，深入研究了模糊控制器的解析结构，并证明了这两类模糊控制器等价于一种变结构的非线性 PI 控制器与相应的非线性控制偏置之和，并且在其输入论域上是单调递增、连续且有界的。

Whereas fuzzy control has been playing a bigger and bigger role in traffic signal timing, many parameters, like the shape of membership functions and their distribution upon the whole universe of the discourse, plus the determination of universe width and fuzzy rules set, are always set up bluntly ahead of time. Worse yet, once done, all parameters will remain unchanged in the whole course.

但由于经典模糊控制器的参数，例如隶属度函数的形状及其在论域上的分布，论域范围的确定以及模糊规则集往往是预先根据人的经验确定，且一经确定在整个控制过程中就不再改变。
